Specification of Letters Patent.

Patented Dec. 1'7, 1907.

Application-filed October 4. 1907- Seri'al No. 395.940.

' liimbus, in the county of Franklin'and State of Ohio, has invented certain new and useful Improvements 'in Tank-Cars, of which the following is 'a specification.

My invention relates to improvements in tank cars, especially in tank cars of the kind shown in my Patent No. 864,377 issued August 27, 1907.

It contemplates improvements in the construction for maintaining the tank block iny operative position, whereby said construction is greatly strengthened; it further contemplates improvements in the construction of the underfraine adjacent the ends thereof, whereby said end construction is strengthened, simplified and cheapened; it further contemplates improvements in the tank saddle at the bolster and at the cross bearer; it further eoiitemplates improvements in the construction of the center sill, whereby the same is strengthened and cheapened.

The foregoing and other objects are contemplated hymy improvements all of whichwill Abe clearlyset forth in the description and claims.

ln the drawings which are hereto attached and hereby made apart of this specification, Figure 1 is a side View partly in section of the underl'rame construction of the tank car; Fig. 2 is an upper plairview of the underframe wustiiictiou; Fig. 3 is a perspective ol" the construction at a cross-bearer: Fig. 4 is a. view showing the develolnnent of the tank saddle; Fig. 5 is a view ol" the construction of the tank saddle at the point where the wooden bearings for the tank arey positioned; Fig. 6 is a View of the reinforcing construetioii for positioning the tank block in the center sill; Fig. 7 is a vertical transverse section at a bolster; Fig. S is a vertical -transverse section at cross-bearer; Fig. Q is an end View ol" the underl'rame; Fig. 10 is a view showing one corner of thc undcrframe construction, .illustrating the slitting of the side sill for seating the tank block, and also the arrangement ol' the push pocket.

l'nasmuch as all of my improvements are fmtures oli' the underlramc construction, l have not deemed it necessary to illustrate a tank, iuasnuich as the position and arrangement of the tank will be readily miderstood; l'urtl fr, l have not deemed it i'iecessaryto 'phragm plateswhich will hereafter be deillustrate the trucks, except the outline of the wheels. n Referring to the drawings, 1 designates the center sill construction, which is clearly" disclosed in Fig. 3, in which it appears that the center sill is made up p referably of two webs 2 and 3, having riveted on the outer side thereof adjacent their upper edges the angles 4 and 5, and having riveted at their lower edges on opposite sides thereof the angles 6, 7,- S, and 9; the angles which are riveted to the lower edge of e'ach web are made wide for the purpose of giving a lirin support to the. web, and the angle riveted along the upper edge of the web is also made wide for the purpose of giving adequate support to t-he cover plate 10 upon which the tank supports are positioned. The wide angles also afford larger supporting bases for the diascribed, whereby the underfraine construction. is greatly strengthened. The cover plate 1() is placed on top of the built-up center sill just described, andv is `riveted to the outwardly extending [langes of the angles secured adjacent the upper edges of the center sill webs, as described. The cover plate is not carried to the cxtreme ends of the underframe, for the reason that the'tank block is let into the center sill construction, and for the further reason that it is not deemed essential in my construction to continue the cover plate completely to the end.

At intervals on ther center sill, there are located erOss-bearers 11, 12, and over the trucks are provided holsters 13 and 14;. The cross-bearer construction is clearly disclosed in Figs. 3, t and 5, in which 15 is the tank saddle, formed of the plate shownin -1 a plate of metal is eut to conform essentially to the outline of Fig. 4, and rivet holes shown generally at 16 are made therethrough; a portion of the plate is then eut or stamped out forming the inwardly extending recess 17, and the transverse recess 1S, said re- 10i cesses forming essentially a T-shaped opening in the plate;- leaving the extensions 19 .and 20 at the sides of the recess 17 and above the recess 18. The extensions 19 and 2O are then vreferably bent at a right angle with 10 the' llane ofthe plate, as appears in Fig. 5; both extensions may be bent in the saine direction if desired, or in opposite directions, as shown iu Fig. 5. the latter construction giving greater support to the wooden bearil` ing Strip 21 for the tank which is placed be- K tween said extensions after they are bent at a right angle, and which is secured thereto by rivets inserted through the'rivet holes shown at 22 and 23. The bearing strips 2] lare braced against a lateral or a twisting movement by the said extensions 19`and 20,

and they' rest upon the lower edge of the' transverse. recess 18;- they are further supefported from beneath, and the general construction at thevcross-bearer is also further strengthened,l by the angles 24 and 25, which are `bent to conform to the curvature of the u per edge of the plate 15, and are secured t ereto by the rivets 26 inserted through the curved row of rivet holes shown generally at 27 in Fig. 4. It will be noted that the tank saddle 15 is a continuous plate cut to the degree of curvature required upon its upper edge and slit and bent as shown in Figs. 4 and 5 especially for the purpose of receiving the Wooden bearing strips, `and bracing the same against a lateral or twisting movement; Y and said plate is further provided with the angles at each side adjacent its upper edge, whereby the tank saddle is greatly strengthened, and" the wooden bearing strips 21 are more firmly supported.

Adjacent each end ofits lower edge the. tank saddle plate l5 is provided with the rivet holes 16 for the reception ofthe rivets 27 to secure said tank saddles to the crosse bearer diaphragm 2S. The diaphragm 28 is flanged in the manner shown generally in my patent hereinbeforementioned, and isshaped to adapt itself to the contour of the outer side of one of the built up members forming the -center sill, to which it is' riveted at 29, as

appears clearly in Fig. 3. The diaphragm 2 8 therefore fits snugly against the center sill web and the angles riveted thereto, and

its. upper edge is riveted to the tank saddle plate 15, as described, thereby forming a very strong construction at the ends of the tank saddle to support the same. The crossbearer diaphragms are Jfurther strengthened and supported by the dia )hragm plate 55, secured at its ends to the ange on the diaphragm, and being positioned beneath the center sill, as appears clearly in Fig. f2; .a

similar diaphragm plate is shown at the bolster at 56 1n Fig. 7, and it'isprovided for a similar purpose.

cover late 10 on the center sill construction,

and t at preferably a plurality oflongitudinal bearlng strips'21 are positioned in the upper edge of the tank `saddle plate. The bearing strips 21 are shown broken away, and it should be stated that these strips may be made to extend the entire length of the tank, or short strips may be provided at each cross-bearer, and at the bolster,'at the desire of the operator. It will be further understood that the order in which the stamping It will further. be notedv that the tank saddle plate 15 rests vupon the may be done .and the rivet holes made in the plate shown in Fig. 4 maybe determined by the operator athis pleasure, there'being no necessity in the orderV mentioned above.

lt will be seen that the tank saddle is curved appropriately to receive the lower portion of the tank, and to embracev the same, whereby a rolling or 'lateral motion of the tank is prevented, further, the wooden bearing strips tend to prevent longitudinal movement of the tank and the consequent wearing away of the tank struc-ture. A side view of the cross-bearer is shown in Fig. 8.

At the bolsters 13 and 14, the tank saddle is built up in a similar manner to that described at the cross-bearers g the tank saddle at the bolster is shown in Fig. 7 and designated at 30, and inasmuch as the construe tion is the-same as that described for the tank saddle at the cross-bearer, no further description will be necessary. It will be noted that the wooden bearing strips are positioned at the bolster in the same manner as at the cross-bearer. However, it will further be noted that at the bolster the parts are provided in duplicate as shown clearly in- Fig. 2 at 31 and 32, whereby the structure is made much stronger.

In Fig. 6 is shown the construction -for positioning the tankblock 33 at a preferred 95 point between the bolster and the end sill 34 I seat the tank block 33 in the centerA sill by slitting down through the center sill webs a preferred' distance at separated points on said webs, and then cutting out or bending laterally the portion between the slits, so as to leave in the upper edge of each web a recess, into which the tank block is adapted to Y be let and to be supported thereby both from beneath and at the forward and rear sides thereof. l then provide a reinforcing construction by bending the ngle 35 to make the same conform to the outline of the recess in the upper cdgeof the center sill web, as appears clearly in Fig. 6.

When the slitted por-tion is bent laterally as mentioned above, the shelf formed thereby would furnish a support for the tank block, in which case one ofthe angles hereinafter described may be omitted; however, I prefer to provide an angle at each side of the center sill web, both shaped to conform to the recess formed therein`,`one of ,these angles being shown at 35, another at 36. These. angles are then secured to the center sill web by rivets shown at 37 and 38. An gles 39 and 40 are also lprQvided in a similarA manner on the other center sill web preferably through the outer of the two angles on a center sill web I provide a b olt hole 41 125 through which is adapted to be inserted a bolt to secure the tank-block to its seat. The foregoing construction is seen to furnish a broad base 42 for the tank block, and 4 also broad and firm supporting walls both rearwardly and forwardly, whereby the tank block is securely positioned and firmly supported." The tank block is further supported lin the side sill 43, saidiside sill being slit down and the slitted portion then bent laterally as shown at 44. A This construction provides a broad, strong base for supporting the end of the tank block, and the walls 45 and 4G support the tank block both rearwardly and forwardly. This construction greatly strengthens thetank block and is an improvement over the tank block construction shown in my said patent.

Adjacent the ends of theunderframe I provide the sideusills, one being indicated at- 43, the remaining side sills being formed in a similar manner; as shown in the drawings, the side sill 43 is preferably a channel with the flanges extending outwardly, which is secured at one end to the bolster construction as seen at 47, and at its other end is secured to the end sill 34 in a manner clearly shown'in Fig. -10l The end sill andside sill meet at a right angle, and at 4S .is shown an angular cover plate riveted to the said sills; I also provide at `the junction of the said sills a push pocket 49, secured to the side sill at 5() and'to the yend sill at 51, forn1- ing a tie to secure the said sills together. The push pocket shown at 52, answers a well known purpose, and need not be further described.' The end sill 34 is strengthened at its junction with the center sill by the angles 53 and 5 4, secured to the ends of the center` sill webs and to the inner face of the end sill.

The end construction of the underframe is' thus seen to comprise the bolster, the tank block let into the center sill and the side sills and supported therein both from beneath and forwardly and rearwardly; also the end sillwhich is firmly secured to the center sill and the side sills. This construction involves the use of fewer parts than are shown in my said patent, and at the same time makes a construction which is firmer `.construction of greater strength and durability, and to provide a construction whichl can be built more rapidly and at less expense.
